# Software Requirements (Version 2.0.1) ## 1 Purpose This page captures the **mandatory hardware and signal‑level requirements** for the upcoming firmware/software release of the Firmware. It serves as a reference for testers, installers and customers to verify that their hardware stack and wiring meet the minimum specifications before flashing the new version. ## 2 Hardware Prerequisites * **Gearbox Control Unit (GCU):** Devices with serial numbers GCU2202001 and up require a hardware upgrade to address some of the manufacturing isues *(Mandatory)* * **Signal‑conditioner board:** Required only when interfacing with **DCT GS7D36SG** speed sensors. *(Mandatory for DCT GS7D36SG installations)* ## 3 Required Signal Inputs | Signal | Source | Connection Method | Notes | | ----------------------------------------------- | ----------------------------------- | ------------------------------------- | ------------------------------------- | | **Brake‑pedal position** | Hydraulic switch or position sensor | Analog IN **or** CAN | On/Off signal | | **Engine RPM** | Crank/Cam sensor or ECU | Frequency IN **or** CAN | | | **Throttle position (TPS)** | ECU / DBW | Analog IN **or** CAN | | | **Accelerator pedal position sensor (PPS)** | ECU | Analog IN **or** CAN | | | **MAP sensor** | ECU | Analog IN **or** CAN | kPa | | **Injector pulse width** *or* **Engine torque** | ECU | Frequency IN (PW) **or** CAN (torque) | Provide either PW (µs) or torque (Nm) | ## 4 DCT GS7D36SG‑Specific Requirements * Install the **signal‑conditioner board** between the gearbox speed sensors and the GCU. ## 5 Test log | Transmission | Status | |--------------|--------| | GS7D36SG | Tested | | DQ500 | | | DQ250 | | | DL800 | Tested | | 7DT45 (PDK) | Tested | | TR9080 | | ## 6 Software implemented features/bug fixes ### Transmission support - General * Improved reliablilty of valve control ### Transmission support - Dual clutch * Reimplemented closed loop pull away (take up) * Added static tables for clutch pressure-duty and rpm-duty for clutch pressure * Improved closed loop shifint method * Improved handling of clutch by wire during driving * Improved ability to pull away using clutch by wire * Added feature start from 1st gear after stop * Added limit of adaptations based on the transmission temperature ### Communication * Improved Canbus handling of trafic * Improved F80 DCT preset for CANbus * Improved MoTeC support * Added implementation for ProSpeed MoTeC communication protocol ### OEM TCU Support * 8HP45 and 8HP70 Added support for OEM TCU over canbus * Added diagnostics for BMW 8HPxx transmissions * 911 997.2 PDK Added draft of support ## 7 Nottice of obsolecence In the upcomming releases following functions are going to be removed and are no longer supported: * ZF 4HP transmission * NSX transmission * Mercedes 722.6 transmission * Aisin AA80E transmission * Aisin A960E transmission ## 8 Change Log | Rev | Date | Author | Summary | | ---- | ----------- | ------------- | ----------------------------------------- | | 0.1 | 2025‑07‑10 | AK | Initial draft created |
